Application iiled September 26, 1904. Serial No. 226,008.

To all whom it may concern:

Be it known that SAMUEL .IAMEs PORT, secretary oi Limited Company,residing at 314 Hag-ley road, Birmingham, in the countyoi Warwick,England, a subject oi the King oi Great Britain, has invented certainnew and useiul Improvements in and Relating to Means for ConveyingSounds to the Ears, oi which the following is a specification.

This invention relates to improvements in means for suspending on theears of an operator sound conducting tubes, and also relates to theparticular construction and arrangement ol the tube so suspended.

The invention comprises the production of an ear piece, means forsuspending the same in position, and a ilexible tube for conveyingsounds to the ear piece.

The invention imther comprises the production of a crank shaped tubeadapted to iit into the cavity of the ear, a clip for suspending thesame in position, and tubes for conveying sounds from any desired placeto the crank shaped member.

The object in view is the provision oi means for conveying sound fromany desired point to the ear, and lor suspending the soundconductingmeans upon the ear.

W ith these and other objects in view the invention comprises certainnovel constructions, combinations, and arrangements of parts as will behereinafter described and claimed.

In the accompanying drawingzFigure l. is a plan view oi a soundconducting device formed according to the present invention, the earpieces being shown in section to better disclose the invention. Fig. 2is an edge view oi Fig. l. Fig. 3 is an enlarged detail, fragmentaryview oi one oi the sound conducting tubes forming part oi the presentinvention, parts being broken away to better disclose the invention.Fig. 4 is a slightly modified form of my invention, the same bein gshown in section to better disclose the invention.

I provide by my invention a light weight attachment which can besuspended from the ears of an operator for conveying sound from anypreferred point to the operator. u

My improved appliance when used by telephone exchange annunciator boardoperators as asubstitute for the inet-allie head gear and breast plateharness, renders the operation less exhausting and thereiore assist theoperator in being continually in that bright, wakeiul and activecondition, so necessary in attending to the duties oi' a telephoneexchange call-girl.

I will now proceed to describe with reference to the accompanyingdrawings lthe manner in which the various parts of my invention areconstructed, assembled and used.

At the lower end oi the tubes 11e-m, I provide a suspending ring j towhich is secured a Y-shaped member d. To the Y-shaped member d issecured a pipe l which is adapted to convey sound l'rom any desiredpoint to the interior of the Y-shaped member d. A suitable binding ringor nut L is provided lor holding the tube l in correct position. Securedto the arms lz oi the Y-shaped member d are flexible tubes ori-m whichare adapted to convey sound from the interior of the Y-shaped member dto the crank shaped member or tube e.

The upper ends of the tubes m-m are adapted to receive the end oi thecrank shaped member c as clearly seen in Fig. 3 oi the drawing. Themember c is threaded at its upper end and has secured thereon an earcavity nozzle s which is adapted to enter the ear cavity and have thesides thereof iinpinge against the sides ol the ear so as to prevent anysound l'rom entering the ear except that which comes through the tubesm-m and through the aperture in the ear cavity nozzle s. It will beobserved that the member e has a deep bend at f in its upper end whichpermits the device to allow the ear cavity nozzle s to snugly fit in theear without pressing the lower part oi the ear which will beaccommodated in the bent-out portion f.

In order to suspend the member e in proper position for permitting theear cavity nozzle s to snugly [it in the ear, I provide a clip n. Theclip n is preferably made in a loop shape, and is secured to areciprocating sleeve u. The sleeve u is positioned on the lower part oithe member e and adapted to reciprocate thereon so as to permit thepositioning oi the loop it in any desired position ior accommodatingvarious sized ears. A suitable securing means as set screw 13 is used tohold the sleeve u and clip n in proper position alter having beenproperly adjusted. As seen in Fig. el, I may provide a slightly modifiedform of means ior conveying sound into the ear. Instead of using the earcavity nozzle s, I provide cushion o which impinges against the ear andthus prevents any sound from entering the ear cavity except that whichpasses through the crank shaped member c/. The upper end oi the crankshaped member e/ is threaded similarly to the crank shaped member e ioradjusting the position of the cushion Z, and also the position oi theclip n/. It will be observed that in the modilication shown in Fig. 4that the clip n is secured to the upper end ol' the crank shaped membere and adapted to be moved back and l'orth for adjusting the same.

In operation the user would suspend the device upon his ears by passingthe two ear loops n over his ears, the ear cavity nozzle s would thengently press against the inner surface of the ears, so that soundreaching the member @from the tubular arms m enters the ears ol' theoperator. A person by the suspension of the U-shaped frame on his ears,would be able to receive a message, and yet have both hands iree lor usein recording the received message or for other use` i Having nowparticularly described and ascertained the nature of my said invention,and in what manner the same s to be performed what I claim is;-

1. In a receiver, a rigid tube bent at one end und having its other endArttztched to a iexible tube which is adapted to communicate with a,receiver'. a rigid clip adapted to pass over and rest upon the ear, saidclip being provided with means that is adapted to slide over the rigidtube and is adjustable thereon for holding the end of the rigid tubedirectly opposite the cavity 0f the eur, and an extension reaching intothe cavity of the ear for conveying sound into the inner part of theear.

2. In a receiver, an ear cushion, an adjustable crankshaped conduit stempassing through said cushion, :t flexible tube connecting said conduitstem and said receiver, and an ear clip adjustably secured to saidconduit stem for supporting the same in position.

In testimony whereof I atlix my signature in the presence of twoWitnesses.
